Jerome Fine replies:
There are probably two simple options:
(a) First boot the DX floppy which contains a DL.SYS device driver,
then BOOT DL: While this method takes a bit longer than (b) below,
at least you can see what you are doing.
(b) A bit more direct is to copy the software boot block from block
zero of the RL02 to block zero of the RX01 floppy. This will then
complete the boot operation from the RL02 media. I would strongly
suggest that you do this with a separate RX01 media which you use
just for this purpose. By the way, Megan Gentry suggested this a while
back. It is certainly a useful method to quickly substitute one boot
hardware for another when the boot ROMs do not have the choice
you want to use.
Sincerely yours,
Jerome Fine
